lNKlNG-PAD.

SPECIFIGATION forming part of Letters Patent No. 672,120, dated April16, 1901.

Application iiled April 28, 1900.

To a/ZZ whom it may concern:

Be it known that I, FREDERICK CARL, a citizen of the United States,residing at Washington, in the District of Columbia, have inventedcertain new and useful Improvements in Inking-Pads, of which thefollowing is a specification, reference being had therein to theaccompanying drawings.

Figure 1 is a central vertical section of an inking-pad embodying myimprovements. Fig. 2 is a section of the pad proper or ink absorbing anddelivering part. Fig. 3 is a side view of the clamping-ring detached.Fig. 4 is a side view of the base part detached. Fig. 5 is a bottom viewof the complete device. Fig. 6 is a top view of the ink-absorbing feltdetached. Fig. 7 is a bottom view of the pad-supporting plate detached.Fig. 8 is an edge view of the same. Fig. 9 is a plan view of thebase-rim. Fig. 10 is a plan View of the clamping-ring detached. Fig. 11is a section, and Fig. 12 is a top View, of a modified form of theinking felt pad.

In the drawings, A indicates the bed-piece or base. It is preferablymade ring-like in form, one side being cut or broken, as shown. at a,and the ends at the cut being suitably remote from each other. The outersurface' at a' is slightly tapering for a purpose to be described. At a2there can be a slight bead at the bottom to serve as a stop and to widenthe bottom surface. Near the upper edge and on its inner side it has ahorizontal ange as. The vertical part extending up is made tapering inthe form of a flange, as at a4. l

The pad proper or inkabsorbing and sup plying part is indicated by C.This is composed of a thick mass of felt, which in the constructionshownin Fig. 1 and others eX- tends continuously from the top surface cto' the bottom surface c. This thick disk'of feltv is cut at theperiphery to a suitable depth, asI a half-inch or more, as shown at c2.

D is a suitable dexible securing means or jacket for the felt or otherbody of the pad. In its preferred form and as illustrated it consists ofa ring-like strip of strong woven fabric, such as canvas, the innerdiameter of which is much less than the diameter of the felt disk. Thisfabricis placed in the cut at c2 and secured by one or more rows ofstitches,

Serial No. 14,772. (No model as at d, and extends outwardly from thefelt.

A felt body of this sort can be secured to the base in any of a numberof ways. As shown, I employ a felt-supporting plate or disk B. This isof a diameter somewhat smaller than that of the iiange a4 of thebase-rim A and is adapted to rest upon the horizontal liange a3. Betweenthe plate B and the base A are interposed springs E, which preferablyare made and arranged as shoWn-that is, of curved flat elastic platesand each riveted at e to the plate B and having its free ends e' placedso as to rest upon the flange a3. The outwardly-extending woven-fabricband or jacket Dis adapted to be turned down and snugly fitted againstthe outer flaring surface a of the base, and after the pad is put inplace and this band is thus arranged the clamping-ring F is slippeddownward over the fabric, and as it moves down it tightly grips thefabric and stretches it, drawing the felt down firmly. The splitbase-ring yields sufficiently to allow the proper downward movement ofthe ring F, and its elasticity insures that the grip of the rim upon thefabric and the pad shall be firmly retained.

There are numerous advantages incident to a construction and arrangementof the parts such as I have shown and described and which will be fullyunderstood upon acomparison with earlier devices-for instance, such -asI have shown in my application, Serial No. 716,776, filed the 13th dayof May, 1899. I

have in the present instance succeeded in providing a pad which shallreceive the rapid blows of a postmarking and stamp-canceling stampwithout imparting shocks to the hand Another important advantageincident to the use of the present device lies in the exposure of thefelt surface at the top without the employment of a woven thread fabricsuch as has been generally employed for the purpose of holding the feltin proper position.

IOO

A body of felt, such as that at C, is not liable to be cut or marled bythe blows of the stamp, which, as is well known, is formed with sharpcutting-dies and with a sharp outer ring which is expected to receiveink and print circles upon the envelops or other articles. By attachingthe woven fabric D to the peripheral part of the felt I am permitted touse a very strong cloth, such as can vas,which could not be employed ifit were to lie over the upper surface of the pad, because ofits beingimpervious to ink. Moreover, by following this course I can make the padreversible, and thus insure a use practically twice as prolonged aswhere one surface only is available. The fabric D is so situated as toprotect the stamp from coming in contact with the metal of the base. Theclamping-ring F is made as thin as possible, and the pad is expandedlaterally, so that there is practically no liability of accidentallystriking any of the metal parts with the stamp.

The modified pad shown in Figs. Il and 12 illustrates that instead ofmaking a cut in the periphery of a thick mass of felt to receive theattaching fabric two somewhat thinner pieces can be used and stitched tothe opposite sides of a strong-cloth holder, and many of the purposes ofthe invention can be attained with such a pad.

In several respects there can be modification without departing from thecharacteristic features of the invention. rPhe resiliency can beprovided by employing rubber blocks in place of the metal springs E, orsprings of either sort can be dispensed with and still retain a superiorpad if it has the exposed felt at its upper operative side with anatt-aching device secured to the pad at points below the top surfacethereof or in such way as to hold the felt firmly and yet leave itexposed on the top.

Instead of the woven fabric D other forms of attaching devices can beused, as a series of cords or threads or a thin light felt or otherequivalent.

While I have shown and described the basering A as split and theinclosing device or ring F as solid, it will be understood that therecan be inversion in this respect and the part F can be made elastic andexpansible and serve for holding the felt pad firmly in position.

What I claim is- 1. An inking-pad, having at its upper op` erative sidea mass of exposed felt, an attaching fabric secured to the periphery ofthe felt, and a base to which the fabric is secured.

2. An in king-pad having at its u pper operative side a mass of exposedfelt, an attaching fabric inserted into the body of the felt at a placebetween the top and bottom surfaces of the felt and secured therein, asupporting base or bed, and means for securing the fabric to the base,substantially as set forth.
